ok well i have a 2001 mustang gt w/ a built bottom end with v2 sq w/ aftercooler....75 mm tb/plenum, afm pipe, 3.125 pulley, x pipe, 90 mm lightning maf...etc....i have 38 lb injectors and i'm using tr7ix's for spark plugs and i have a 255 walboro with a kb bap as well.....how much power will the stock fuel rails hold? i don't think i'll be pushing any more than 420 to the wheels if even that so do you think the stock fuel rails will be fine???? or should i upgrade fuel rails??

pretty sure with your current setup you'll need bigger injectors before you need upgraded fuel rails.

i totally agree with that...i know i'll need larger injectors but when i talked to james at RWTD he said he can increase the size of the injector at WOT.....he said the limit of 38s are around 450 rwhp or so

I think the stock rails will be fine. Unless you plan on making bigger power in the future, which most people end up doing. If that's the case, might as well upgrade when you get the chance.

most people upgrade when they are 500+ just to be on the safe side.

Fore is coming out with a new set of rails for 2v's. they are using my old PI intake for R&D. they are going to have the KB disc thing already built into them so you dont pop the rail pressure sensor. they are also some of the best looking rails i have ever seen. the shop is 1 mile from my job so if you want i can get you a good price on a pair of them.

get rid of that damn walbro fuel pump. its a time bomb. they arent designed for a returnless system and will burn out.
